TR-2 PPI PVC Range Composition Listing of Qualified Ingredients

2. Stress-rupture data obtained on pipe extruded on commercial equipment from a PVC
composition with components falling within the ranges given in Part A, except for liquid stabilizer
and calcium carbonate which must be at the maximum levels, confirm that the use of the alternate
PVC resin yields the anticipated HDB of 4,000 psi for water for 73 o F (23 o C). The data must be
obtained in accordance with TR-3 and evaluated according to ASTM D 2837.
a. Experimental listing of a new PVC resin shall be available upon the presentation of acceptable
E-2 or higher-grade data for one lot of pipe. The experimental listing expires one year
following the effective date. The owner of an experimental listing must understand
there is a potential risk in commercial sale of an experimental ingredient in case it
does not meet all theTR-2 requirements.
b. Standard listing, with no expiration date, shall be available upon the presentation of acceptable
E-10, or higher-grade data for one lot and E-2, or higher-grade data on two other lots.
Part B.2 Heat Stabilizer, Process Aid, Colorant and other Components Not
Complying to Part A
Any heat stabilizer, process aid, or colorant and any calcium stearate, paraffin wax,
polyethylene wax, titanium dioxide or other ingredient not meeting the guidelines given in
Part A will be accepted for listing when the appropriate stress-rupture data confirm the
anticipated HDB of 4,000 psi for water at 73°F (23°C) when evaluated according to ASTM
D 2837. The data shall be obtained on pipe extruded on commercial equipment and from
a composition that falls within the ranges listed in Part A except for the subject component
that shall be at the maximum proposed use level. In cases where the minimum proposed
use level is greater than zero, the composition shall be formulated in two lots with the
subject component at the maximum proposed use level and with the subject component at
the minimum proposed use level. The data must be obtained in accordance with TR-3 and
evaluated according to ASTM D 2837.
a. Experimental listing of the component shall be available upon the presentation of
acceptable E-2 or higher-level data for one lot of pipe that has been formulated with
the subject component at the maximum proposed use level. The experimental
listing expires one year following its effective date. The owner of an experimental
listing must understand there is a potential risk in commercial sale of an
experimental ingredient in case it does not meet all the TR-2 requirements.
b. Standard listing, with no expiration date, shall be available upon the presentation of
acceptable E-10 or higher-grade data for one lot and E-2 or higher-grade level data
for two other lots. One of these lots of pipe shall include the subject component at
the minimum proposed use level as required per the above paragraph. Each of
these three lots shall be formulated with different qualified PVC resin.
